34 <application>QtWebEngine</application> integrates
35 <application>chromium</application>&quot;s web capabilities into Qt. It
36 ships with its own copy of ninja which it uses for the build if it cannot
37 find a system copy, and various copies of libraries from ffmpeg, icu,
38 libvpx, and zlib (including libminizip) which have been forked by the
39 <application>chromium</application> developers.

44 <note><para>By default, ninja will use all online CPUs +2 (if at least
45 4 exist), even if they are not available to the current task because the
46 build terminal has been restricted with 'taskset'. To work around this,

175
176 <para>
177 <option>NINJAJOBS=4 make</option>: If you patched system ninja in LFS to
178 recognize the NINJAJOBS environment variable, this command will run system
179 ninja with the specified number of jobs (i.e. 4). Among the reasons why
180 you might want to do this are: building on a subset of CPUs, either to
181 measure the build time for that number of processors or to run other
182 CPU-intensive tasks on other cores, or to improve the build speed on a
183 less-well endowed 4-core machine. On a machine with a powerful CPU and
184 plenty of RAM, running N+2 jobs (the ninja default for 4+ cores) for the
185 large working sets of the C++ compiles in this package is typically only
186 marginally faster than running N jobs at a time. But for a machine with
187 less memory it can be much slower.
